Description
This is another bug caused by the recent planar audio addition in libav.
FFmpeg does not have the bug though, so as with the AC-3 bug this does seem to be a bug with MPlayer's implementation of planar audio rather than a bug in libav.
Sample file: http://lipqpj.1fichier.com/ (click the button down the bottom "Telecharger le fichier" for instant download)
Command line:
mencoder dts71.m2ts -oac lavc -of mpeg -ovc lavc -o output.mpeg
What happens is that MEncoder just exits without doing anything or displaying an error code. Here is the complete output:
MEncoder (C) 2000-2012 MPlayer Team

This is FFmpeg ticket #1827, work-around is to add -channels 8 to the command line.

Ah ok, cool. Will be great to see this fixed since my main usage case needs -channels 2.
By the way, the specific FFmpeg revision that caused this bug was e88ca80; 82db8ee works perfectly.
